The fight will take place on the organization’s upcoming event at University Arena (“The Pit”) in Albuquerque, N.N. The event’s main card airs on Showtime.

Reis, a 23-year-old Brazilian jiu-jitsu black belt, pushed his career mark to 5-0 with a unanimous-decision victory over Bryan Caraway at “EliteXC: Unfinished Business” in July. It was the Philadelphi-based fighter’s third consecutive win in the EliteXC.

After the event, EliteXC Head of Fight Operations Jeremy Lappen told MMAjunkie.com (www.mmajunkie.com) that Reis was under consideration for a title shot later in the year.

It’ll now come against Quach, a veteran fighter who’s experienced a remarkable career turnaround. Although he began his professional career with a 6-8-1 record, Quach has since posted nine consecutive victories, including EliteXC victories over Bobby McMaster and UFC veteran Doug Evans.

With the crowning of a 140-pound champion, EliteXC’s only men’s weight class without a champion will be the light-heavyweight division. The organization also expects to implement titles in two women’s divisions — 130 and 140 pounds — within the next year.

The Sept. 20 EliteXC event will be headlined by Albuquerque fighter Joey Villasenor, though his opponent hasn’t been determined. Also slated for the card is Cristiane “Cyborg” Santos vs. Yoko Takahashi, and Paul Daley vs. Lyman Good. Dave “Pee Wee” Herman and Alberto Crane are also expected to compete against currently unannounced opponents.
